FIELD OF THE TECHNOLOGY

At least some embodiments disclosed herein relate to artificial neural network (ANN) training through processing power of parked vehicles.

BACKGROUND

Artificial neural networks (ANNs) are artificial intelligence (Al) systems that are loosely modeled from biological neural networks. ANNs can be considered Al systems since such systems can artificially learn to perform tasks. An ANN is one of many different types of tools of machine learning. An ANN can artificially learn through example input and generally without being programmed with task-specific rules. For example, when an ANN is used for speech recognition, it may learn to identify audio signals that contain the spoken word “hello” by analyzing example audio signals that are known to contain the spoken word “hello”. The results of the computations by the ANN can then be used to identify the spoken word “hello” in other audio signals. In an image recognition example, an ANN may learn to identify images that contain a person by analyzing example images that are known to contain a person. The output of the ANN can then be used to identify a person in other images.

Besides speech and image recognition, ANNs can be used for just about any machine learning task that includes supervised learning. And, such ANNs have been used for medical diagnosis, solving business and technical problems, machine translation, network filtering, filtering in big data systems, playing video games, and real-time generation of new parts of video games and multi-media. ANNs are even being developed to guide decision making in vehicular automation and self-driving cars.

An ANN is based on a set of connected nodes, which are often called artificial neurons. The connected nodes loosely model biological neurons of a brain. The connections between nodes are analogous to synapses in a brain. However, the connections (often called edges) are part of a mathematical model opposed to actual physical elements that transmit signals to and from biological neurons. The artificial neurons or nodes are also a part of the mathematical model and are loosely analogous to biological neurons that can receive signals via synapses and then process and send the signals via synapses.

In an ANN, a connection between nodes can include a number. And, an output of a node can be computed from a function (such as a non-linear function) including a sum or a derivative of a sum of its inputs, or more specifically, a sum or a derivative of a sum of its input connections. Also, artificial neurons and edges often have a weight that adjusts with a learning process. The weight can increase or decrease the number at an edge. Artificial neurons can also have a threshold such that a number of an edge is input for the neuron only if the aggregate of inputs of the neuron exceeds the threshold. Also, typical in an ANN, its nodes or artificial neurons are organized into layers. And, different layers of the ANN can perform different transformations on their inputs. An ANN can include an input layer and an output layer, and transformations occur from the input layer to the output layer. Also, an ANN can include one or more intermediate layers between the input layer and the output layer.

Also, any of the apparatuses, computing devices, vehicles, sensors or cameras, and/or user interfaces described herein can include a computer system of some sort (e.g., see computing systems 104 and 204 as well as master computing device(s) 140 and master computing device 142). And, such a computer system can include a network interface to other devices in a LAN, an intranet, an extranet, and/or the Internet. The computer system can also operate in the capacity of a server or a client machine in client-server network environment, as a peer machine in a peer-to-peer (or distributed) network environment, or as a server or a client machine in a cloud computing infrastructure or environment.

As shown in FIG. 1 , the networked system 100 can include at least a vehicle 102 that includes a vehicle computing system 104 that includes a ANN training client application 106 associated with an ANN training system (also referred to herein as the ANN training client 106). The vehicle 102 can also include a body and controllable parts of the body (not depicted), a powertrain and controllable parts of the powertrain (not depicted), a body control module 108 (which is a type of ECU), a powertrain control module 110 (which is a type of ECU), and a power steering control unit 112 (which is a type of ECU). The vehicle 102 also includes a plurality of sensors (e.g., see sensors 114 a to 114 b), a GPS device 116, a plurality of cameras (e.g., see cameras 118 a to 118 b), and a controller area network (CAN) bus 120 that connects at least the vehicle computing system 104, the body control module 108, the powertrain control module 110, the power steering control unit 112, the plurality of sensors, the GPS device 116, and the plurality of cameras to each other.

Also, as shown, the vehicle 102 is connected to the network(s) 122 via the vehicle computing system 104. Also, shown, vehicles 130 to 132 and the master computing device(s) 140 (which includes the master computing device 142) are connected to the network(s) 122, and, thus, are communicatively coupled to the vehicle 102. The ANN training client 106 included in the computing system 104 can communicate with the master computing device(s) 140 as well as the master computing device 142.

In some embodiments, the networked system 100 can include a master computing device (e.g., see master computing device 142). The master computing device can be a single computing device or multiple computing devices depending on the embodiment. Either way, the master computing device can at least include a controller (e.g., see controller 144) as well as a communication interface (e.g., see communication interface 146) that is communicatively coupled to the controller. As shown in FIG. 1 , the controller 144 can include an ANN trainer 148. The ANN trainer 148 can include computer hardware and/or software that is configured to train an ANN as well as control training of the ANN when at least some of the training tasks are delegated to another computing system or device via an ANN training client (e.g., see ANN training client 106).

With respect to FIG. 1 , the controller 144 of master computing device 142 can be configured to control training of an ANN (such as via the ANN trainer 148). Not shown in FIG. 1 , the controller 144 can be distributed amongst multiple networked computers as can the ANN trainer 148 be distributed amongst multiple networked computers. The training of the ANN can be performed at least partially in separate parts by respective computing devices of parked vehicles (e.g., see computing systems 104 and 204 of respective vehicles 102 and 202). However, in some embodiments, the vehicles used by the controller 144 are not necessarily parked. Although, it may be preferred to use a parked vehicle, since its computing resources would not be used by driving modes of the vehicle; thus, freeing up the computing resources for performing tasks for training the ANN.

The controller 144 can also be configured to separate computing tasks of training the ANN into separated tasks, such as via execution of the ANN trainer 148. The controller 144 can also be configured to assign at least some of the separated tasks to respective selected computing devices of parked vehicles (e.g., see computing systems 104 and 204 of respective vehicles 102 and 202), such as via execution of the ANN trainer 148. The controller 144 can also be configured to receive and assemble results of the separated tasks to train the ANN, such as via execution of the ANN trainer 148. Also, the controller 144 can be configured to train the ANN according to the results of the separated tasks, such as via execution of the ANN trainer 148. The training of the ANN, the training of parts of the ANN, or at least some tasks of the training of the ANN can be performed according to a delta rule.

The communication interface 146 of the master computing device 142, which is communicatively coupled to the controller 144, can be configured to send the assigned tasks to the respective selected computing devices of the parked vehicles. The communication interface 146 can also be configured to receive, from the respective selected computing devices, the results of the assigned tasks.

In some embodiments, the controller 144 is configured to select a computing device of a parked vehicle according to a notification received from the parked vehicle indicating that the vehicle is parked. The selection according to the notification can be done via the ANN trainer 148 as well. Also, the notification received from the parked vehicle can further indicate that the vehicle is authorized for training the ANN. In some embodiments, the notification includes the indication that the vehicle is authorized for training of the ANN without including an indication that the vehicle is parked.

In such embodiments and others, the controller 144, such as via the ANN trainer 148, can be configured to deselect the computing device of the parked vehicle according to a notification received from the parked vehicle indicating that the vehicle is probable to be driven within a time period. The probability that the vehicle is to be driven within a time period can be computed by a device of the vehicle or another computing device and can be based on a rule based algorithm, or artificial intelligence technology (such as an ANN or a decision tree), or any combination thereof.

Also, in such embodiments and others, the controller 144 can be configured to reassign, to another one of the selected computing devices, a task for training the ANN assigned to the deselected computing device when the controller has received the notification that the vehicle is probable to be driven within the time period and a result for the task has not been received from the deselected computing device prior to the time period. The reassignment can be performed via the ANN trainer 148.

In some embodiments, the controller 144 can be configured to maintain, in a queue, respective links to the selected computing devices of the parked vehicles. And, the controller 144 can be configured to remove, from the queue, a respective link of one of the selected computing devices when the one of the selected computing devices is deselected. The aforesaid maintenance and removal of links can be performed via the ANN trainer 148.

In such embodiments, the controller 144 can be configured to select a computing device of a parked vehicle according to a notification received from the parked vehicle indicating that the vehicle is parked. The controller 144 can also be configured to maintain, in the queue, the selected computing device.

The controller 144 can also be configured to deselect the computing device of the parked vehicle according to a notification received from the parked vehicle indicating that the vehicle is probable to be driven within a time period, and remove, from the queue, the deselected computing device. The controller 144 can also be configured to reassign, to another one of the selected computing devices, a task for training the ANN assigned to the deselected computing device when the controller has received the notification that the vehicle is probable to be driven within the time period and a result for the task has not been received from the deselected computing device prior to the time period. The aforesaid selection, maintenance, deselection and/or reassignment can be performed via the ANN trainer 148 as well.

Also, although readiness of a vehicle computing system to be selected has been shown to be when the host vehicle is parked, it is to be understood that another state of the vehicle or another state of a part of the vehicle can be the indicator that the vehicle computing system is ready for performing a task of training an ANN. Also, for the most part of this disclosure, a vehicle being in a state wherein it is about to driven is described as a deciding factor in deselecting its computing system for performing a task of training an ANN. However, it is to be understood that another state of the vehicle or another state of a part of the vehicle can be the indicator that the vehicle computing system is ready to be deselected for performing a task of training an ANN.

Besides vehicle computing devices (e.g., see computing systems 104 and 204 of vehicles 102 and 202 respectively), the vehicles disclosed herein include vehicle electronics, including at least electronics for the controllable parts of a body, the controllable parts of a powertrain, and the controllable parts of power steering. The vehicles disclosed herein can include controllable parts of the body and such parts and subsystems can be connected to a body control module (e.g., see module 108). The body can include at least a frame to support the powertrain. A chassis of the vehicle can be attached to the frame of the vehicle. The body can also include an interior for at least one driver or passenger. The interior can include seats. The controllable parts of the body can also include one or more power doors and/or one or more power windows. The body can also include any other known parts of a vehicle body. And, the controllable parts of the body can also include a convertible top, sunroof, power seats, and/or any other type of controllable part of a body of a vehicle. The body control module can control the controllable parts of the body.

Also, vehicles disclosed herein can include the controllable parts of a powertrain. The controllable parts of the powertrain and its parts and subsystems are connected to a powertrain control module (e.g., see module 110). The controllable parts of the powertrain can include at least an engine, transmission, drive shafts, suspension and steering systems, and powertrain electrical systems. The powertrain can also include any other known parts of a vehicle powertrain and the controllable parts of the powertrain can include any other known controllable parts of a powertrain. Also, power steering parts that are controllable can be controlled via a power steering control unit (e.g., see control unit 112).

UI elements described herein, such UI elements of a mobile device, another type of computing device, or a vehicle can include any type of UI. The UI elements can be, be a part of, or include a car control and can be, include or be a part of an electronic system. Also, a UI can be a gas pedal, a brake pedal, or a steering wheel. Also, a UI can be a part of or include an electronic device and/or an electrical-mechanical device and can be a part of or include a tactile UI (touch), a visual UI (sight), an auditory UI (sound), an olfactory UI (smell), an equilibria UI (balance), or a gustatory UI (taste), or any combination thereof.

Sensors described herein (e.g., see sensors 114 a to 114 b) and cameras described herein (e.g., see cameras 118 a to 118 b) of vehicles can include any type of sensor or camera respectively configured to sense and/or record one or more features or characteristics of the plurality of UI elements or output thereof or any other part of a vehicle or its surroundings. A sensor or a camera of a vehicle can also be configured to generate data corresponding to the one or more features or characteristics of the plurality of UI elements or output thereof or any other part of the vehicle or its surroundings according to the sensed and/or recorded feature(s) or characteristic(s). A sensor or a camera of the vehicle can also be configured to output the generated data corresponding to the one or more features or characteristics. Any one of the plurality of sensors or cameras can also be configured to send, such as via a CAN bus, the generated data corresponding to the one or more features or characteristics to a computing system (such as computing system 104 or 204) or other electronic circuitry of a vehicle.

A set of mechanical components for controlling the driving of a vehicle described herein can include: (1) a brake mechanism on wheels of the vehicle (for stopping the spinning of the wheels), (2) a throttle mechanism on an engine or motor of the vehicle (for regulation of how much gas goes into the engine, or how much electrical current goes into the motor), which determines how fast a driving shaft can spin and thus how fast the vehicle can run, and (3) a steering mechanism for the direction of front wheels of the vehicle (for example, so the vehicle goes in the direction of where the wheels are pointing to). These mechanisms can control the braking (or deacceleration), acceleration (or throttling), and steering of the vehicle. The user indirectly controls these mechanism by UI elements (e.g., see other components 216 of vehicle 202 shown in FIG. 2 ) that can be operated upon by the user, which are typically the brake pedal, the acceleration pedal, and the steering wheel. The pedals and the steering wheel are not necessarily mechanically connected to the driving mechanisms for braking, acceleration and steering. Such parts can have or be proximate to sensors that measure how much the driver has pressed on the pedals and/or turned the steering wheel. The sensed control input is transmitted to the control units over wires (and thus can be drive-by-wire). Such control units can include body control module 108 or 220, powertrain control module 110 or 222, power steering control unit 112 or 224, battery management system 226, etc. Such output can also be sensed and/or recorded by the sensors and cameras described herein (e.g., see sensors 114 a to 114 b or 217 a to 217 b and cameras 118 a to 118 b or 219 a to 219 b). And, the output of the sensors and cameras can be further processed, such as by the ANN training client 106, and then reported to external computing devices (such as the master computing device(s) 140) for cumulative data processing.

In a vehicle, such as vehicle 102 or 202, a driver can control the vehicle via physical control elements (e.g., steering wheel, brake pedal, gas pedal, paddle gear shifter, etc.) that interface drive components via mechanical linkages and some electro-mechanical linkages. However, more and more vehicles currently have the control elements interface the mechanical powertrain elements (e.g., brake system, steering mechanisms, drive train, etc.) via electronic control elements or modules (e.g., electronic control units or ECUs). The electronic control elements or modules can be a part of drive-by-wire technology.

Drive-by-wire technology can include electrical or electro-mechanical systems for performing vehicle functions traditionally achieved by mechanical linkages. The technology can replace the traditional mechanical control systems with electronic control systems using electromechanical actuators and human-machine interfaces such as pedal and steering feel emulators. Components such as the steering column, intermediate shafts, pumps, hoses, belts, coolers and vacuum servos and master cylinders can be eliminated from the vehicle. There are varying degrees and types of drive-by-wire technology.

Also, the plurality of UI can include a braking control (e.g., a brake pedal or a GUI or another type of UI equivalent such as a voice input UI for braking). The plurality of UI can also include a throttling control (e.g., a gas pedal or a GUI or another type of UI equivalent such as a voice input UI for accelerating the vehicle). Also, the plurality of UI can include a transmission control (e.g., manual gearbox and driver-operated clutch or a GUI or another type of UI equivalent such as a voice input UI for changing gears of the vehicle).

In some embodiments, the electronic circuitry of the vehicle can include electronics for an automated driving system.

In some embodiments, the computing system of the vehicle (such as computing system 104 or 204) can include a central control module (CCM), central timing module (CTM), and/or general electronic module (GEM). Also, in some embodiments, the vehicle can include an ECU, which can be any embedded system in automotive electronics that controls one or more of the electrical systems or subsystems in the vehicle.

The computing system 204 can be a machine capable of executing a set of instructions (sequential or otherwise) that specify actions to be taken by that machine. Also, while a single machine is illustrated for the computing system 204, the term “machine” shall also be taken to include any collection of machines that individually or jointly execute a set (or multiple sets) of instructions to perform a methodology or operation. And, it can include at least a bus (e.g., see bus 206) and/or motherboard, one or more controllers (such as one or more CPUs, e.g., see controller 208), a main memory (e.g., see memory 210) that can include temporary data storage, at least one type of network interface (e.g., see network interface 212), a storage system (e.g., see data storage system 214) that can include permanent data storage, and/or any combination thereof.

FIG. 4 illustrates a flow diagram of example operations of method 400 that can be performed by aspects of the networked system depicted in FIGS. 1 to 3 , in accordance with some embodiments of the present disclosure. For example, the method 400 can be performed by master computing device(s) 140, master computing device 142, master computing device 302, and/or master computing devices 320 to 322.

In FIG. 4 , the method 400 begins at step 402 with separating, by a controller, computing tasks of training of an ANN. The step 402 can be performed by a controller of a system for training of an ANN (such as a system including master computing device(s) 140, master computing device 142, master computing device 302, and/or master computing devices 320 to 322). At step 404, the method 400 continues with selecting, by the controller, a computing device of a parked vehicle according to a notification received from the parked vehicle indicating that the vehicle is parked. The vehicle does not necessarily need to be parked in some embodiments. In such embodiments, the notification may merely indicate that the computing device of the vehicle is authorized to be used by the controller.

At step 406, the method 400 continues assigning, by the controller, at least some of the separated tasks to the selected computing device. At step 408, the method 400 continues sending, by a communication interface coupled to the controller, the assigned tasks to the selected computing device. At step 410, the method 400 continues with receiving, by the communication interface, results of the assigned tasks from the selected computing device. At step 412, the method 400 continues with assembling, by the controller, the results of the assigned tasks to train the ANN. The controller in some example cases can assemble the results with other results of assigned tasks performed at other computing devices of other vehicles to train the ANN. Also, such results can be assembled with results from training tasks performed by the controller or another computing device that is not a part of a vehicle, such as a mobile device of a user who has authorized the mobile device to assist with training the ANN. At step 414, the method 400 continues with training, by the controller, the ANN according to the results.

At step 416, the method 400 continues with deselecting, by the controller, the computing device of the parked vehicle according to a notification received from the parked vehicle indicating that the vehicle is probable to be driven within a time period. Step 416 can occur after the training of the ANN at step 414 or at a time prior to the training. For example, the step 416 can occur prior to the communication interface receiving the results of the assigned tasks from the selected computing device at step 410. In such an example situation, after the step 416 of the deselection of the computing device, another computing device can be selected. For example, as shown in FIG. 4 , step 404 can be repeated for another computing device after deselection of the computing device at step 416. And, then at step 406, the at least some of the separated tasks initially assigned to the computing device can be reassigned to another computing device (such as another computing device of another vehicle that was recently discovered to be parked). Also, as shown in FIG. 4 , steps 406 to 410 can be repeated until the controller is ready to assemble the results of the assigned tasks at step 412.

FIG. 5 illustrates a flow diagram of example operations of method 500 that can be performed by aspects of the networked system depicted in FIGS. 1 to 3 , in accordance with some embodiments of the present disclosure. For example, parts of the method 500 can be performed by a computing system of a vehicle such as computing system 104 or 204.

In FIG. 5 , the method 500 begins at step 502 with generating and outputting, by a first electronic system of a vehicle, first vehicle information related to whether the vehicle is parked. The first electronic system can be made up of any one or more of the vehicle control modules or ECUs described herein, any one or more of the cameras, GPS devices, or sensors described herein, or any combination thereof.

At step 504, the method 500 continues with receiving, by a vehicle computing device of the vehicle (such as a vehicle computing device of or including the vehicle computing system 104 or 204), the first vehicle information from the first electronic system. At step 506, the method 500 continues with determining, by the vehicle computing device, whether the vehicle is parked according to the first vehicle information received from the first electronic system. When it is determined that the vehicle is parked, the method 500 can continue, at step 508, with sending, to at least one master computing device (e.g., see master computing device(s) 140, master computing device 142, master computing device 302, and master computing devices 320 to 322), a notification indicating that the vehicle is parked and selectable by the at least one master computing device for executing at least one task for training an ANN. Otherwise, the method 500 can continue, at step 502, with generating and outputting, by the first electronic system, vehicle information related to whether the vehicle is parked.

At step 510, the method 500 continues with receiving and executing, by the vehicle computing device, at least one task for training the ANN assigned to the vehicle computing device by the at least one master computing device while the vehicle is parked.

FIG. 6 illustrates a flow diagram of example operations of method 600 that can be performed by aspects of the networked system depicted in FIGS. 1 to 3 , in accordance with some embodiments of the present disclosure. For example, parts of the method 600 can be performed by a computing system of a vehicle such as computing system 104 or 204. As shown, the method 600 can begin subsequent to method 500, and step 602 can depend on the occurrence of step 510 of method 500.

At step 602, the method 600 continues with generating and outputting, by a second electronic system of the vehicle, second vehicle information related to whether the vehicle is probable to be driven within a time period. The second electronic system can be made up of any one or more of the vehicle control modules or ECUs described herein, any one or more of the cameras, GPS devices, or sensors described herein, or any combination thereof.

At step 604, the method 600 continues with receiving, by the vehicle computing device, the second vehicle information from the second electronic system of the vehicle. At step 606, the method 600 continues with determining, by the vehicle computing device, whether the vehicle is probable to be driven within a time period according to the second vehicle information received from the second electronic system. When it is determined that the vehicle is probable to be driven within a time period, the method 600 continues, at step 608, with sending, to the at least one master computing device, a notification indicating that the vehicle is probable to be driven within a time period. Also, at step 610, the method 600 continues with terminating, by the vehicle computing device, execution of the at least one task for training the ANN when it is determined that the vehicle is probable to be driven within the time period. Otherwise, as shown in FIG. 6 , the method 600 continues with the step 602 of generating and outputting, by the second electronic system, vehicle information related to whether the vehicle is probable to be driven within a time period.

In some embodiments, it is to be understood that the steps of methods 400, 500, or 600 can be implemented as a continuous process such as each step can run independently by monitoring input data, performing operations and outputting data to the subsequent step. Also, such steps for each method can be implemented as discrete-event processes such as each step can be triggered on the events it is supposed to trigger and produce a certain output. It is to be also understood that each figure of FIGS. 4 to 6 represents a minimal method within a possibly larger method of a computer system more complex than the ones presented partly in FIGS. 1 to 3 . Thus, the steps depicted in each figure of FIGS. 4 to 6 can be combined with other steps feeding in from and out to other steps associated with a larger method of a more complex system.

The ANNs described herein can be used by a drive-by-wire process of a vehicle, or an automated driving system of the vehicle, or any combination thereof.
